-
The extraction of lactic acid(HA) with primary amine N1923(RNH2) has been studied by means of a slope method and IR spectrophotometry at (298±1) K. The composition of the extracted complex was found to be RNH2HA. The equilibrium constant of extraction was determined as lg Kex=1.63. The results showed that lower temperature was favorable for the extraction.
